Hi,
I have a Acer 4500 Laptop.... It had a locked harddrive and bios so I reset the bios by unplugging the bios battery and it worked... Installed new harddrive and got windows installed... I then started having problems with it shutting down around 30-40 percent of installing windows... So I got frustrated and decided that maybe it was a cooling issue.. So I got the biggest box fan I could find in my house and turned it on and it got through the install... So Now Im having similar problems with it... After about 1 hour of use the screen goes black and the PC is still on, Like the lights and everything are on but the screen is black.... I then have to hold down the power button to get it to turn off. Any help would be greatly appreciated!! Thanks

Ok... I think the CPU is just heating up so i took off the heatsink... It was very loose I might add and looking at the heatsink pad it looks as if there is some sort of thermal tape applied and then in the middle where the CPU meets the heat sink is a rectangle cutout the same size of the CPU... Should I take all of the thin thermal tape off? It really doesnt seem to be like tape at all as it comes of really easily but it is covering the complete bottom of the heat sink except for the retangular area where the heatsink meets the CPU where it seems as if regular thermal compound has been applied. Ill go ahead and go out and get some good thermal compound... Should I remove the thermal tape and just stick with the regular dab of thermal compound?

You don't want to use just a standard thermal compound as most of them will have silicone in them. You need something that will have some silver in it.

That could definitely be your problem as the CPU does not like getting too warm. :flowers:

So, get some good thermal compound and reassemble that heatsink so that it is secure on the CPU. There are usually screws on the heatsink, somewhere.

Good luck with it. :thumbsup:

Thermal compound will cost somewhere in the area of $5-10...money well spent (even if you only use it once).

Ok so far ive got the heat sink back all together with some good silver thermal compound and its giving me a reading of 60 Celcius being the high one and the low is 50 degrees Celcius... Are those good readings?

Damn!!!!! Ok now went to restart because I installed an update and the screen went black again.... So I turned it back on and nothing comes on screen... Power buttons light up and all but nothing on screen... Looks like ill have to wait around 20 min or so for me to turn it back on...

When you had it apart, did you blow out the fan ductway and vents?
